rlwrap is a readline wrapper, a small utility that uses the GNU readline library to allow the editing of keyboard input for any other command. It maintains a separate input history for each command, and can TAB-expand words using all previously seen words and/or a user-specified file.

The xterm program is the standard terminal emulator for the X Window System. It provides DEC VT102/VT220 and Tektronix 4014 compatible terminals for programs that can't use the window system directly. If the underlying operating system supports terminal resizing capabilities (for example, the SIGWINCH signal in systems derived from 4.3bsd), xterm will use the facilities to notify programs running in the window whenever it is resized.

Screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Each virtual terminal provides the functions of the DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (e.g., insert/delete line and support for multiple character sets).

Fosfat is a C library for providing read-only
access to a Smaky formatted disk. Currently, only
a tool and a FUSE extension that use this library can be used for reading a directory and copying a file. Smaky is a
system developed in Switzerland at the EPFL (Ecole
Polytechnique Fédérale de Lausanne).

dvtm brings the concept of tiling window
management, popularized by X11-window managers
like dwm, to the console. As a console window
manager, it tries to make it easy to work with
multiple console based programs like vim, mutt,
cmus, or irssi. dvtm is intended to be used where
X11 isn't available or over SSH. In conjunction
with dtach, it can be seen as a lightweight
alternative to GNU screen.

vttest is a program to test the compatibility (or to demonstrate the non-compatibility) of so- called "VT100-compatible" terminals. Additional tests are provided for analysis of vt220/vt420 terminals and variants of xterm.

The Useful Terminal I/O library is a C++
alternative to ncurses for working with
terminfo-defined terminals. Included are raw terminfo string access and output, an efficient buffered output system, and a keyboard driver.

AKFAvatar is a fancy graphical user interface for text oriented applications where an avatar appears on the screen and provides information in a balloon. It also supports recorded audio files. Applications for AKFAvatar can be written in Lua, and there are interfaces for C and Free Pascal.
A number of ready-to-use applications and modules are provided, including a text viewer and a module that makes question-answer exercises. For POSIX-compatible operating systems there is a man page viewer and a terminal emulator, which makes it possible to run many existing terminal-based programs in this fancy environment.
